Disclosed a regulator for clutch actuator. The regulator for clutch actuator includes a housing having a cylindrical damping space inside, a first fluid path interconnecting the damping space and a master cylinder, and a second fluid path interconnecting the damping space and a an operating cylinder. The regulator further includes a flexible valve member contained in the damping space for reducing vibrations. The flexible valve member comprises a first inflow guiding portion configured to receive and guide fluid from the first fluid path. The first inflow guiding portion has a plurality of through holes such that elastic deformation of the first inflow guiding portion reduces vibration when fluid flow into the cylindrical damping space from the master cylinder.

A deresonated fluid system may include a pressurizable fluid line having distal, opposite line ends with the fluid line extending between the line ends. A source may be configured to apply variations in pressure of fluid in the fluid line having a frequency appropriate for producing a standing wave in the fluid line between the line ends. A fluid coupler having opposite first and second coupler ends may be attached to the fluid line in a medial portion of the fluid line between the line ends. A flow acceleration ramp may be formed about an inside of the first coupler end. An artificial acoustic shoulder may be formed about an inside of the second coupler end. The artificial acoustic shoulder may define a substantially central orifice in fluid communication with the flow acceleration ramp.

Various connection units are disclosed. The connection unit can be configured to straighten a flow of air, such as to reduce the distance before the flow of air becomes substantially laminar. The connection unit can include a drag reduction unit. The drag reduction unit can be configured to redirect airflow to the center of the connection unit. The connection unit can include a wake diverting component configured to lift air away from the periphery of the connection unit and/or redirect the airflow towards a radial center connection unit.

An internal combustion engine with an exhaust tract and with a secondary air system which has a secondary air conduit through which secondary air can flow in an injection direction. The secondary air can be introduced into the exhaust tract. A valve element is arranged in the secondary air conduit and has a first flow resistance along the injection direction and a greater second flow resistance along an opposite backflow direction, as a result of which a backflow taking place in the backflow direction can be limited. The valve element has a plurality of rotationally symmetrical impact bodies which are arranged consecutively along the injection direction and are connected to one another. The valve element is arranged in a length region of the secondary air conduit which is limited by a structural element of the internal combustion engine which is formed separately from the valve element.

A flow conditioning device for incrementally stepping down pressure within a piping system is presented. The invention includes an outer annular housing, a center element, and at least one intermediate annular element. The outer annular housing includes an inlet end attachable to an inlet pipe and an outlet end attachable to an outlet pipe. The outer annular housing and the intermediate annular element(s) are concentrically disposed about the center element. The intermediate annular element(s) separates an axial flow within the outer annular housing into at least two axial flow paths. Each axial flow path includes at least two annular extensions that alternately and locally direct the axial flow radially outward and inward or radially inward and outward thereby inducing a pressure loss or a pressure gradient within the axial flow. The pressure within the axial flow paths is lower than the pressure at the inlet end and greater than the vapor pressure for the axial flow. The invention minimizes fluidic instabilities, pressure pulses, vortex formation and shedding, and/or cavitation during pressure step down to yield a stabilized flow within a piping system.

The invention relates to a fluid line (1), comprising a pipe (2), which has an inlet-side end segment (3) having a first connector (5) and an outlet-side end segment (4) having a second connector (10), wherein a cavity (17) bounded in the radially inward direction by at least one auxiliary element (16) is formed in the pipe (2). The problem addressed by the invention is that of minimizing the requirements for the suction performance of a pump that is used to convey a liquid through the pipe. This problem is solved in that a volume reduction element (18) is arranged in the cavity (17) at least in the region of the outlet-side end segment (4).
